From Turkish arnavut, from Ottoman Turkish آرناوود (arnavut, “an Albanian”). Entered Ottoman Turkish from the Byzantine Greek ethnonym Arvanitis (Αρβανίτης) after the syllable cluster van was rearranged through metathesis to nav giving the final Turkish forms as Arnavut and Arnaut. Meanwhile in Greek the name Arvanitis was derived from the original term Alvanitis (Ἀλβάνίτης) as a process of rhotacism Alv- into Arv-. In return Alvanitis stems from the name Alvanos (Ἀλβάνος) Albanian, from Ancient Greek Ἀλβανοί (Albanoí).

Arnaut (plural Arnauts)

^ Ulrich Theißen (2007), Zeitschrift für Balkanologie (in German), page 90:

Der ursprüngliche Name ἀλβανίτης (abgeleitet von ἀλβάνος) wurde im Neugriechischen zu ἀρβανίτης […]. In türkischer Vermittlung erfuhr die Silbe -van- eine Metathese zu -nav-, so dass die türkische Form des Namens für die Albaner arnavut bzw. arnaut lautet. In dieser Form gelangte das Wort ins Bulgarische (BER I/1971: 15).

The original name ἀλβανίτης (derived from ἀλβάνος) became ἀρβανίτης in Modern Greek […]. In being mediated to Turkish, the syllable -van- underwent metathesis to -nav-, so that the Turkish form of the name for the Albanians is Arnavut or Arnaut. In this form, the word passed into Bulgarian (BER I/1971: 15).
^ Noel Malcolm (1998), Kosovo: A Short History, London: Macmillan, page 29:

The name used in all these references is, allowing for linguistic variations, the same: 'Albanenses' or 'Arbanenses' in Latin, 'Albanoi' or 'Arbanitai' in Byzantine Greek. (The last of these, with an internal switching of consonants, gave rise to the Turkish form 'Arnavud', from which 'Arnaut' was later derived.)
